Information processing apparatus and control method

Abstract

An information processing apparatus includes: a memory which temporarily stores a program of a system; a first processor which executes face authentication processing to detect an area of a face image with a face captured therein from a captured image captured by an imaging unit and to authenticate whether or not a person of the detected face image is a registered user based on information on the detected face image and information on a face image of the registered user; and a second processor which executes the program of the system to boot the system from a standby state based on a fact that authentication by the face authentication processing is successful.

What is claimed is: 
     
         1 . An information processing apparatus comprising:
 a memory which temporarily stores a program of a system;   a first processor which executes face authentication processing to detect an area of a face image with a face captured therein from a captured image captured by an imaging unit and to authenticate whether or not a person of the detected face image is a registered user based on information on the detected face image and information on a face image of the registered user; and   a second processor which executes the program of the system to boot the system from a standby state based on a fact that authentication by the face authentication processing is successful,   wherein when the authentication by the face authentication processing is unsuccessful, the first processor executes the face authentication processing again, and when executing the face authentication processing repeatedly due to failures of the authentication by the face authentication processing, the first processor stops the face authentication processing based on the number of times the face authentication processing is executed.   
     
     
         2 . The information processing apparatus according to  claim 1 , wherein
 the first processor executes person detection processing to detect presence of a person by detecting the area of the face image with the face captured therein from the captured image, and when the presence of a person is detected by the person detection processing, the first processor moves from the person detection processing to the face authentication processing, and   the first processor stops the face authentication processing based on a fact that the number of times the face authentication processing is executed has reached a preset number of times since the presence of the person was detected by the person detection processing.   
     
     
         3 . The information processing apparatus according to  claim 2 , wherein when stopping the face authentication processing due to failures of the authentication by the face authentication processing, the first processor moves to the person detection processing. 
     
     
         4 . The information processing apparatus according to  claim 3 , wherein when the presence of a person is detected by the person detection processing after stopping the face authentication processing, the first processor determines whether or not the number of persons that exist changes, and when determining that the number of persons that exist changes, the first processor moves from the person detection processing to the face authentication processing again. 
     
     
         5 . The information processing apparatus according to  claim 4 , wherein when the presence of the person is no longer detected by the person detection processing after stopping the face authentication processing, the first processor continues the person detection processing without moving to the face authentication processing, and when the presence of a person is detected, the first processor moves from the person detection processing to the face authentication processing. 
     
     
         6 . The information processing apparatus according to  claim 2 , wherein the person detection processing is processing lower in power consumption than the face authentication processing. 
     
     
         7 . The information processing apparatus according to  claim 2 , wherein
 a frame rate when detecting the area of the face image with the face captured therein from the captured image in the person detection processing is lower than that in the face authentication processing, and   when moving from the person detection processing to the face authentication processing and from the face authentication processing to the person detection processing, the first processor switches the frame rate.   
     
     
         8 . The information processing apparatus according to  claim 1 , wherein
 the second processor executes login authentication processing to authenticate whether or not to allow login to the system based on the face image detected from the captured image captured by the imaging unit after booting the system, and   the face authentication processing executed in the standby state before booting the system is processing lower in power consumption than that in the login authentication processing.   
     
     
         9 . The information processing apparatus according to  claim 8 , wherein the frame rate when detecting the area of the face image with the face captured therein from the captured image in the face authentication processing executed in the standby state before booting the system is lower than that in the login authentication processing. 
     
     
         10 . The information processing apparatus according to  claim 1 , wherein the first processor executes user registration processing to register information based on a face image of a user using the information processing apparatus. 
     
     
         11 . A control method for an information processing apparatus including a memory which temporarily stores a program of a system, a first processor, and a second processor, the control method comprising:
 a step of causing the first processor to execute face authentication processing to detect an area of a face image with a face captured therein from a captured image captured by an imaging unit and to authenticate whether or not a person of the detected face image is a registered user based on information on the detected face image and information on a face image of the registered user;   a step of causing the second processor to execute the program of the system to boot the system from a standby state based on a fact that authentication by the face authentication processing is successful;   a step of causing the first processor to execute the face authentication processing again when the authentication by the face authentication processing is unsuccessful; and   a step in which, when executing the face authentication processing repeatedly due to failures of the authentication by the face authentication processing, the first processor stops the face authentication processing based on the number of times the face authentication processing is executed.
